Long story short: their customer support is poor, they don’t stand behind their products, and they aren’t honest about either.
I bought two electric Airsoft rifles for Dave and Tom for Christmas. Tom’s was fine; David’s was poorly designed and built. I got an RMA for it the day after Christmas, then had to fight with them for months before getting a partial refund. First they ignored me, then they claimed that the rifle had been damaged in return shipping (but couldn’t produce a UPS claim), then they claimed that it was damaged before shipping.
I eventually had to dispute the charge with my bank. The whole thing was a big hassle and not worth the few bucks that I might have saved by buying from them instead of a more reputable vendor.
